Current Research-Nano-enabled Sensors

One thing molecules do particularly well at the nanoscale is to recognize certain target molecules. Chemical reactions occur with clock-work regularity and specificity that cannot be matched. For many sensor applications, it appears that atoms don’t wear out. In our research in this area, we are trying to identify a number of promising sensor systems that can be exploited. We have designed, built and tested a number of transducers that give an electronic or optical signal related to nano-scale binding events. This work is highly collaborative and is performed under Purdue’s Center for Sensing Science and Technology.
